Why did my light fixture start turning off and on randomly? How do I fix it?

The light fixture above our kitchen table just started turning itself off and on* randomly. It's quite annoying. (Darnit, there it goes again!)
This fixture is a pretty standard one where there's a piece that's embedded in the ceiling (where the bulbs go) and a translucent glass cover. It holds two bulbs and is attached to a dimmer switch. Currently the bulbs are two incandescents at 60W each.
My suspicion is that some part of it is overheating, though I'm not totally sure of this. When the problem first happened, it only had one working bulb and was set to a dim light. I replaced the bulb figuring it had blown out, and took the opportunity to replace the other one at the same time, so it probably runs a lot hotter now.
The light can stay on for 45-60 minutes or so. Then it'll turn itself off for about 15 minutes. If I leave the switch on, it'll eventually pop back on... and turn off again... ad infinitum.
Circuit breakers are not tripping in the electric box.
I'm no electrician and am not afraid to hire one, but since I bought this house I've learned that a lot of things aren't all that hard to fix yourself. I'm hoping that's the case with this, and if not then I hope to at least have a clue so an electrician can't fleece me.
* - I know "turn itself off and on" is probably not the accurate term. There's no digital switch or anything that reflects the problem -- just an analog dimmer. But "extinguishes and rekindles itself" doesn't sound right either.
